splitting apart pvrusb2-i2c-core - part of it is the driver's I2C

header references are correspondingly updated. Yes, this patch has a
huge pile of checkpatch complaints, but I'm NOT going to fix any of
it. Why? First, I'm moving a large chunk of existing code and I'm
not going to spend time adjusting it to match someone's idea of coding
